"This objectI have attained by the'means which ar hereinafter describedand claimed, andwvhich are illustrated the accompanying drawings, and inwhich similarst'rucltures are indicated by the same numerals.

Insaid'drawings, Fig. 1 isa ve'rtical cenimproved means for "controlling'itsffluid delivery, some of'the elements being shown "in elevation.Fig. 2 is a detail cross section on "the broken .line 2 2 of Fig. 1 ofthe the piston-valve being shown in elevation. Fi '3 is a cop planof-the valve-casing.

fineexa'mple whiche'mbodies my improveme'nt's is that which isillustrated in Figs.

1 to '3 iiujlusive, being an oil-can adapted for manualfactuation of itscontrolling piston-valve. The oil-can'f8 has communication at thediminished top with the depending neck 6' of a horizontal casing 3 andits included cylinder 2 containing' a conforming reciprocatorypistOnQvalve' "1. An open ended tube 7 has its uppe'r e'nd fitted insaid neck to depend 'at an inclination toward the bo ttoin of the can.The lower end of the neck 6. is widened at 20 and \velded or brazed tothe open top of the can. The numeral 4 denotes a spout mounted in anannular seat 21 on the top ofone end of the casing 3 and communicatingbyway of the delivery-port 5 with the forward part-of the casing whichcontains the cylinder 2, the latter being of'slightly less diameter thanthe diameter of the main casing to the rear, the rear open end of whichhasas'crew-cap 13'provided with a central hole to receive the plungerstem 14 having an outer terminaldisk 15.

Upon the top of the casing 3 at the rear is an upwardly projectingcurved finge'r-,

hold 16, while below said casingis alooped handle 17 on the oil-can 8whose upper part is crimped inwardly to provide a smaller finger-hold 18whose outer interval is filled 'by a stifiening pie e 43, 'whe'reby 11,616,634 r TED E-S ENE when the handle 17 is grasped, the forefinger ofthe user may be "hooked abodt-the up'perfinger-hold 16, -and the fingerneiit thereto inserted-in 'thefin er-hold 18, givjing a secure grip andperl ect 'm'a'nual con-v M1 tothe user While th'e'thum'b on the samehand is'used topres's 'u pon'th'e disk 15 to push it reward-1y in the"operation of "the piston-valve 1.

the'casing by suction draws to the rear the valve 1, and causes suction1n the cylinder 2 and the tube 7, oil rising by Way of the .tube intothe neck 6 and passing thence through the pair of side ports or passages19 (see Fig. 2)'into the casing 3. The'annular space around thediminished part 9 of the valve gives the requisite clearance for the oil.to the ports 19 when the valve 1 has moved to the rearsufliciently.This fills the hollow casing 3' with oil. Subsequent compression of saidspring returns the valve 1, because the push of theplunger istransmitted to the valve by the oil in the cas- 1 spi'ingieacts towa'rdthe right or rear push: ing the plunger-head 12in that direction,

and the partial vacuum thereby caused in ing to' return the valve. Inits return to the front, the rear end of the valve uncovers thedelivery-port 5 and oil is ejected of the latter,

perforate plunger 'l'rom the casing therethrough into the spout 4. V 7Having described'my invention, What I claim as new, and desire to secureby Letters Patent, is:

1. A valvular device, comprising a valvechamber having an interiorcylinder inter mediate its ends and an enlarged springbarrel openinginto one end of the cylinder, the valve-chamber having a port positionedWithin said cylinder intermediate the ends an unconnected imperforatefloating plunger reciprocably fitting said cylinder and having that endopposite the spring-barrel diminished to be limited in itstravelbyimpact with the facing end Wall of the valvdchamber, and a coiled springmounted in said spring-barrel to have one terminal stopped by a shoulderbetween the cylinder and spring-barrel and the terminal bentdiametrically inwardly to serve as a 'lnnlting stop for said plunger,and means for releasably compressing said spring including means forproducing alternate suction and pressure on the plunger.

2. A valvular device, comprising arvalvechamber'having a port at one endand having'a cylinder intermediate its ends, and

having its end' part opposite said port en-' larged at a shoulder toserve as a spring-.

barrel and suction chamber, a coiled spring in said spring barrel havingone end 00- casionally engaged with said'shoulder and having a terminalbent inwardly, an iminsaid spring-barrel fitting it and occasionallyengagingthe outer end ofsaid spring, said spring-barrel having anapertured removable end-closure, said plunger having a stem projectingthrough said apertured end-closure, an unconnected imperforate floatingplunger fitting said cylinder reciprocably to control the delivery 7 ofsaid spring-barrel into' the cylinder, said cylinder having a portintermediate its ends, and the last-mentioned plunger controlling pistonin of said cylinder,

, piston.

said port, being stopped at one limit of its travel by and saidlast-mentioned plunger the inwardly projecting terminal of saidend-closure, said plunger having a stem projecting through the.apertured end-closure, an unconnected lmperforate floating plungerfitting said cylinder reciprocably and stopped at one limit of itstravel by the in -e terminal of said spring, said Wardly turned cylinderhaving a port intermediateits ends controlled by the last-mentionedplunger,

and the cylinder'ivall having at opposite 'sides longitudinal recessesseparated from said port to serve-asconduits communicating and betweenthe ported end of the valve-chamber V and said intermediate port at acertain position of the last-mentioned plunger.

4:. A! device of the character'described,

characterized by the inclusion of a differential cylinder, anunconnected floating one dilierential part of said cylinder, a plungerin the other differential part and a resilient member intcrn'rediatesaid piston and plunger adapted to alternately serve as an elasticcushion for the plunger and as an end-stop for the Signed at Waterloo,.IoWa, this 19th day of June,1923.
